In modern economic conditions, in the absence of state funding for geological exploration related to the determination of reserves of traditional natural raw materials, the optimal solution is to replace it with ash and slag materials. The use of ash and slag material in the compositions of ceramic masses, as a thinning agent, contributes to the production of wall material based on fusible clay. Studies have shown that the optimal amount of ash and slag material (ash) in the compositions for the production of 125 (M125) grade wall material is 25%. A further increase in the ash content in ceramic compositions leads to a decrease in the strength of the product. Obviously, this is due to the fact that the ash under study is not only a thinning agent, but also a burning additive that contributes to the appearance of porosity. It is established that the physical and mechanical properties of ceramic wall material (brick) depend non-linearly on the content of ash and slag material in the composition. To describe the physico-mechanical dependencies on the content of ash and slag material, it is recommended to use a polynomial of the second degree.
